type Extension struct {
	Name        string  `json:"name"`        // Extension package name
	SQLName     string  `json:"sql_name"`    // SQL name used in CREATE EXTENSION

	MinVersion  float32 `json:"min_version"` // Minimum PostgreSQL version required
	Available   bool    `json:"available"`   // Whether extension files are available
	Installed   bool    `json:"installed"`   // Whether extension is installed in database

	Install     func(p pkg.Postgres) error
	IsInstalled func(p pkg.Postgres) bool
	Health      func(p pkg.Postgres) error
